MACHINE FOR CUTTING CHENlLLE CLOTl-l.

SPECIFICATION forming part of Letters Patent N0. 714,646, dated November 25,1902.

Application filed July 1,1902. SerialNo.113,940. (N0 model.)

machines for cutting chenille-cloth; and it consists, essentially, of a frame carrying a stationary bed furnished upon its face with a series of grooves or notches which are adapted to be entered by a corresponding series of revolving cutting-disks carried upon a shaft parallel with said bed and carried in bearings carried by the frame, soarranged that they and the shaft may be moved to or from the bed, as may be necessary to bring the disks into contact with the chenille or to move them away from the chenille when for any reason it may be necessary to discontinue the cutting of the cloth.

My invention consists, further, in the particular means for carrying the cutter-carrying shaft, for driving this shaft, and of a means for sharpening the cutting-disks without removing them or their carrying-shaft from the machine.

1 In the accompanying drawings, forming part of this specification, and in which similar characters of reference indicate similar parts throughout the several views, Figure 1 isa plan of a chenille-cloth-cutting machine embodying my improvements; Fig. 2, an end view of Fig. 1; Fig. 3, a section of Fig. 1 on line A B.

a/is the frame of the machine, which carries upon its top a stationary bed I), which extends from one end of the machine to the other, and the movable bearing blocks a, which carry the ends of the shaft cl, which carries the cutting-disks e.

f represents grooves or notches in the face of the bed I), which mesh with the disks 6, the grooves and disks being arranged to corre spond in number and location with the warpthreads in the chenille-cloth to be cut into strips.

The under sides of the bearing-blocks a carry racks 9, Fig. 3, which are adapted to be engaged by the teeth of segments h, carried on a shaft 2', carried in bearings in the frame a.

jis a lever carried by shaft 2', by means of which this shaft and segments it may be rocked in order to move the bearing-blocks c and the shaft (1 and cutting-disks e toward or away from the bed-plate b.

The chenille to be cut is carried upon an unwinding-roll 70, carried in suitable bearings in frame a. From this roll it passes up over the top of bed 17, as shown in Figs. 2 and 3, then down to the winding-roll Z, which is also carried in suitable bearings inframe a.

The winding-roll Z is driven by a frictionroll m, which carries a spur-gear n, Fig. 2, which is driven by a worm 0 on a shaft p, which carries a bevel-gear r,which gears with and is driven by a bevel-gear s, driven by the main shaft i of the machine.

it is a clutch on shaft 10, by means of which the end of this shaft carrying the worm 0 can be thrown into or out of gear with the driving-gear r.

o is a lever by means of which clutch u can be operated.

to is a hand wheel or crank on shaft 19, by means of which this shaft may be operated by hand in order to adjust the chenille upon the winding-roller before the machine is started.

Upon the main shaft t of the machine is a pulley 1, Fig. 1, which is driven from any suit able counter-shaft by a belt. (Not shown.)

2 is a pulley on shaft i, which drives an endless belt 3. This belt passes over an idler 4, around a pulley 5 on the disk-carrying shaft (1, and over an idler 6. When the shaft (2". and the disks e are moved away from the bed, as before described, the belt 3 is so slackened that the driving of the pulley 5 and the shaft 61 ceases and the hand can be passed down between the bed and cutting-disks in order to rectify any mishaps without danger of accident.

7 is a pulley carried upon the shaft cl, carrying the cutting-disks. This pulley drives a belt 9, which drives a pulley 8, which through a shaft 14: drives a pulley 10, which drives a belt 12, which drives a pulley 11, fast to a shaft 15, which carries a series of grindingwheels 16, which are adapted to be brought into contact with the disks 6 when these latter are dull in order to sharpen them all si-.

carried by said shaft, means for moving said blocks toward or away from said bed, a pulley on the shaft carrying said disks, a driving-pulley, two idler-pulleys, an endless belt 20 passing under said driving-pulleys and over said idlersand the pulley on said disk-carry-- ing shaft, and means for driving said drivingpulley.

2. The combination with the cutter-diskcarrying shaft and the cutters of a chenillecloth-cutting machine and means for driving said shaft, of a pulley on said shaft, a belt driven by said pulley, apulley driven by said belt, a shaft carrying said pulley, a pulley carried by said latter shaft, a belt driven by said latter pulley, a pulley driven by said belt, a shaft carrying and driven by said pulley, a series of grinding-wheels carried by said shaft, and levers pivoted to the frame of the machine for carrying the grinding- 5 wheel-carryin g shaft.
